Make Profile

In this section:

Introduction

This command will extract continuous profile data based on a line crossing the selected chart(s). The command has two options, make one Along profile or multiple Across profiles. The profiles will be seamless over the edges of the input charts.

The Profile Data part:

Select XY profile dataset in the profile data folder. The output from the command will be saved in the same folder.

The Mode part: 

Options: 
- Along profile 
- Across profile 

Select to extract one along profile or several across profiles. 

The Along Profile parameters part: 

Specify the point spacing in the profile and optionally a start value (Kp) for the profile. 

Point spacing (m): Specify the distance between the points in the profile. A value of zero will use a default spacing. 
Start value (m): Specify a start value (Kp) for the profile. The value will be added to the profile length values.

The Across Profile parameters part:

Specify along spacing, profile length and spacing for the across profiles, and optionally a start distance for the profile. 

Profile spacing (m): Specify distance between across profiles along the specified profile. A value of zero will use a default spacing. 
Profile length (m): Specify the length of each across profile. The across profiles will be half this length on each side of the specified profile. 
Point spacing (m): Specify the distance between the points in the across profiles. The across profile will get one point per specified value. 
Start value (m): Specify a start value for the profile that will be used to calculate the positions of the across profiles. 

The Chart Name part: 

Select from the list which charts to apply. 

The output file with the generated profile contain the length along the profile in a column named Distance. This is the distance along the profile added with the start value. The column KP is the distance in kilometers. 
Across profiles will get a column named AcrossDistance with values from -width to +width. Negative values are on the left hand side of the profile line. 
A start value of the profile length can optionally be added to the profile length. 
Along profiles will also get a column named PointType. The values here will be Vertex or Interpolated. Vertex points are the original points from the input profile, while interpolated are created when executing the command. 

The generated profile data is saved in the project into the same folder as the input profile. Along profiles will get the extension _alongProfile and across profiles will getb the extension _acrossProfiles.
